and with compounds of general formula

wherein X denotes an oxygen atom or an —NH group and Y, Z, R² and R³ are as hereinbefore defined, with the proviso that R² and R³ do not contain any free carboxylic acid, any other free primary or secondary aliphatic amino function or any other free hydroxy function.

The fundamentally two-step reactions are normally carried out as one-pot processes, in which, preferably, in the first step, one of the two components (III) or (V) is reacted with equimolar amounts of the carbonic acid derivative of general formula (IV) in a suitable solvent at lower temperature, then at least equimolar amounts of the other component (III) or (V) are added and the reaction is completed at a higher temperature. The reactions with bis-(trichloromethyl)-carbonate are preferably carried out in the presence of at least 2 equivalents (based on bis-(trichloromethyl)-carbonate) of a tertiary base, for example triethylamine, N-ethyldiisopropylamine, pyridine, 1,5-diaza-bicyclo-[4,3,0]-non-5-ene, 1,4-diazabicyclo[2,2,2]octane or 1,8-diazabicyclo-[5,4,0]-undec-7-ene. The solvents used, which should be anhydrous, may be for example tetrahydrofuran, dioxane, dimethylformamide, dimethylacetamide, N-methyl-2-pyrrolidone, 1,3-dimethyl-2-imidazolidinone or acetonitrile, while if bis-(trichloromethyl)-carbonate is used as the carbonyl component anhydrous chlorohydrocarbons, for example dichloromethane, 1,2-dichloroethane or trichloroethylene are preferred.

Rohr, “Synthesen mit heterocyclischen Amiden (Azoliden)”, Neuere Methoden der Praparativen Organischen Chemie, Volume V, p. 53-93, Verlag Chemie, Weinheim/Bergstr., 1967; P. Majer and R. S.

The coupling is preferably carried out using methods known from peptide chemistry (cf. e.g. Houben-Weyl, Methoden der Organischen Chemie, Vol. 15/2), for example using carbodiimides such as e.g. dicyclohexylcarbodiimide (DCC), diisopropyl carbodiimide (DIC) or ethyl-(3-dimethylaminopropyl)-carbodiimide, O-(1H-benzotriazol-1-yl)-N,N-N′,N′-tetramethyluronium hexafluorophosphate (HBTU) or tetrafluoroborate (TBTU) or 1H-benzotriazol-1-yl-oxy-tris-(dimethylamino)-phosphonium hexa-fluorophosphate (BOP). By adding 1-hydroxybenzotriazole (HOBt) or 3-hydroxy-4-oxo-3,4-dihydro-1,2,3-benzotriazine (HOObt) the reaction speed can be increased. The couplings are normally carried out with equimolar amounts of the coupling components as well as the coupling reagent in solvents such as dichloromethane, tetrahydrofuran, acetonitrile, dimethyl formamide (DMF), dimethyl acetamide (DMA), N-methylpyrrolidone (NMP) or mixtures thereof and at temperatures between −30 and +30° C., preferably −20 and +25° C. If necessary, N-ethyl-diisopropylamine (DIEA) (Hüng base) is preferably used as an additional auxiliary base.

The so-called anhydride process is used as a further coupling method for synthesising compounds of general formula (I) (cf. also: M. Bodanszky, “Peptide Chemistry”, Springer-Verlag 1988, p. 58-59; M. Bodanszky, “Principles of Peptide Synthesis”, Springer-Verlag 1984, p. 21-27). The Vaughan variant of the mixed anhydride process is preferred (J. R. Vaughan Jr., J. Amer. Chem. Soc. 73, 3547 (1951)), in which the mixed anhydride of the carboxylic acid of general formula (VI) which is to be coupled and monoisobutyl carbonate is obtained, using isobutyl chlorocarbonate in the presence of bases such as 4-methyl-morpholine or 4-ethylmorpholine. The preparation of this mixed anhydride and the coupling with amines are carried out in a one-pot process, using the above-mentioned solvents and at temperatures between −20 and +25° C., preferably 0° C. and +25° C.

Coupling a compound of general formula

with a piperidine of general formula

wherein R¹ is as hereinbefore defined.

The reaction is carried out under Schotten-Baumann or Einhorn conditions, i.e. the components are reacted in the presence of at least one equivalent of an auxiliary base at temperatures between −50° C. and +120° C., preferably −10° C. and +30° C., and optionally in the presence of solvents. The auxiliary bases used are preferably alkali metal and alkaline earth metal hydroxides, e.g. sodium hydroxide, potassium hydroxide or barium hydroxide, alkali metal carbonates, e.g. sodium carbonate, potassium carbonate or caesium carbonate, alkali metal acetates, e.g. sodium or potassium acetate, as well as tertiary amines, e.g. pyridine, 2,4,6-trimethylpyridine, quinoline, triethylamine, N-ethyl-diisopropylamine, N-ethyl-dicyclohexylamine, 1,4-diazabicyclo[2,2,2]octane or 1,8-diazabicyclo[5,4,0]undec-7-ene, the solvents used may be, for example, dichloromethane, tetrahydrofuran, 1,4-dioxane, acetonitrile, dimethyl formamide, dimethyl acetamide, N-methyl-pyrrolidone or mixtures thereof; if alkali metal or alkaline earth metal hydroxides, alkali metal carbonates or acetates are used as the auxiliary bases, water may also be added to the reaction mixture as cosolvent.

(d) In order to prepare compounds of general formula (I) wherein all the groups are as hereinbefore defined:

Coupling a carboxylic acid of general formula

wherein all the groups are as hereinbefore defined, with an amine of general formula HNR²R³, wherein R² and R³ are as hereinbefore defined, with the proviso that it does not contain any free carboxylic acid and/or other free primary or secondary aliphatic amino function.

The coupling is preferably carried out using methods known from peptide chemistry (cf. e.g. Houben-Weyl, Methoden der Organischen Chemie, Vol. 15/2), for example using carbodiimides such as e.g. dicyclohexylcarbodiimide (DCC), diisopropyl carbodiimide (DIC) or ethyl-(3-dimethylaminopropyl)-carbodiimide, O-(1H-benzotriazol-1-yl)-N,N-N′,N′-tetramethyluronium hexafluorophosphate (HBTU) or tetrafluoroborate (TBTU) or 1H-benzotriazol-1-yl-oxy-tris-(dimethylamino)-phosphonium hexa-fluorophosphate (BOP). By adding 1-hydroxybenzotriazole (HOBt) or 3-hydroxy-4-oxo-3,4-dihydro-1,2,3-benzotriazine (HOObt) the reaction speed can be increased. The couplings are normally carried out with equimolar amounts of the coupling components as well as the coupling reagent in solvents such as dichloromethane, tetrahydrofuran, acetonitrile, dimethyl formamide (DMF), dimethyl acetamide (DMA), N-methylpyrrolidone (NMP) or mixtures thereof and at temperatures between −30 and +30° C., preferably −20 and +25° C. If necessary, N-ethyl-diisopropylamine (DIEA) (Hüng base) is preferably used as an additional auxiliary base.

The so-called anhydride process is used as a further coupling method for synthesising compounds of general formula (I) (cf. also: M. Bodanszky, “Peptide Chemistry”, Springer-Verlag 1988, p. 58-59; M. Bodanszky, “Principles of Peptide Synthesis”, Springer-Verlag 1984, p. 21-27). The Vaughan variant of the mixed anhydride process is preferred (J. R. Vaughan Jr., J. Amer. Chem. Soc. 73, 3547 (1951)), in which the mixed anhydride of the carboxylic acid of general formula (VI) which is to be coupled and monoisobutyl carbonate is obtained, using isobutyl chlorocarbonate in the presence of bases such as 4-methyl-morpholine or 4-ethylmorpholine. The preparation of this mixed anhydride and the coupling with amines are carried out in a one-pot process, using the above-mentioned solvents and at temperatures between −20 and +25° C., preferably 0° C. and +25° C.

(e) In order to prepare compounds of general formula (I) wherein R¹ is as hereinbefore defined, with the proviso that no free primary or secondary amine is present:

Coupling a compound of general formula

wherein all the groups are as hereinbefore defined and Nu denotes a leaving group, for example a halogen atom, such as the chlorine, bromine or iodine atom, an alkylsulphonyloxy group with 1 to 10 carbon atoms in the alkyl moiety, a phenylsulphonyloxy or naphthylsulphonyloxy group optionally mono-, di- or trisubstituted by chlorine or bromine atoms, by methyl or nitro groups, while the substituents may be identical or different, a 1H-imidazol-1-yl, a 1H-pyrazol-1-yl optionally substituted by one or two methyl groups in the carbon skeleton, a 1H-1,2,4-triazol-1-yl, 1H-1,2,3-triazol-1-yl, 1H-1,2,3,4-tetrazol-1-yl, a vinyl, propargyl, p-nitrophenyl, 2,4-dinitrophenyl, trichlorophenyl, pentachlorophenyl, pentafluorophenyl, pyranyl or pyridinyl, a dimethylaminyloxy, 2(1H)-oxopyridin-1-yl-oxy, 2,5-dioxopyrrolidin-1-yloxy, phthalimidyloxy, 1H-benzo-triazol-1-yloxy or azide group,

with an amine of general formula HNR²R³, wherein R² and R³ are as hereinbefore defined, with the proviso that no free carboxylic acid and/or other free primary or secondary aliphatic amino function is present.

The reaction is carried out under Schotten-Baumann or Einhorn conditions, i.e. the components are reacted in the presence of at least one equivalent of an auxiliary base at temperatures between −50° C. and +120° C., preferably −10° C. and +30° C., and optionally in the presence of solvents. The auxiliary bases used are preferably alkali metal and alkaline earth metal hydroxides, e.g. sodium hydroxide, potassium hydroxide or barium hydroxide, alkali metal carbonates, e.g. sodium carbonate, potassium carbonate or caesium carbonate, alkali metal acetates, e.g. sodium or potassium acetate, as well as tertiary amines, e.g. pyridine, 2,4,6-trimethylpyridine, quinoline, triethylamine, N-ethyl-diisopropylamine, N-ethyl-dicyclohexylamine, 1,4-diazabicyclo[2,2,2]octane or 1,8-diazabicyclo[5,4,0]undec-7-ene, the solvents used may be, for example, dichloromethane, tetrahydrofuran, 1,4-dioxane, acetonitrile, dimethyl formamide, dimethyl acetamide, N-methyl-pyrrolidone or mixtures thereof if alkali metal or alkaline earth metal hydroxides, alkali metal carbonates or acetates are used as the auxiliary bases, water may also be added to the reaction mixture as cosolvent.

The new compounds of general formula (I) according to the invention contain one or more chiral centres. If for example there are two chiral centres the compounds may occur in the form of two pairs of diastereomeric antipodes. The invention covers the individual isomers as well as the mixtures thereof.

The diastereomers may be separated on the basis of their different physico-chemical properties, e.g. by fractional crystallisation from suitable solvents, by high pressure liquid or column chromatography, using chiral or preferably non-chiral stationary phases.

Racemates covered by general formula (I) may be separated for example by HPLC on suitable chiral stationary phases (e.g. Chiral AGP, Chiralpak AD). Racemates which contain a basic or acidic function can also be separated via the diastereomeric, optically active salts which are produced on reacting with an optically active acid, for example (+) or (−)-tartaric acid, (+) or (−)-diacetyl tartaric acid, (+) or (−)-monomethyl tartrate or (+)-camphorsulphonic acid, or an optically active base, for example with (R)-(+)-1-phenylethylamine, (S)-(−)-1-phenylethylamine or (S)-brucine.

According to a conventional method of separating isomers, the racemate of a compound of general formula (I) is reacted with one of the above-mentioned optically active acids or bases in equimolar amounts in a solvent and the resulting crystalline, diastereomeric, optically active salts thereof are separated using their different solubilities. This reaction may be carried out in any type of solvent provided that it is sufficiently different in terms of the solubility of the salts. Preferably, methanol, ethanol or mixtures thereof, for example in a ratio by volume of 50:50, are used. Then each of the optically active salts is dissolved in water, carefully neutralised with a base such as sodium carbonate or potassium carbonate, or with a suitable acid, e.g. dilute hydrochloric acid or aqueous methanesulphonic acid, and in this way the corresponding free compound is obtained in the (+) or (−) form.

The (R) or (S) enantiomer alone or a mixture of two optically active diastereomeric compounds covered by general formula I may also be obtained by performing the syntheses described above with a suitable reaction component in the (R) or (S) configuration.

The starting compounds of general formula (III) may be obtained, if they are not known from the literature or even commercially available, according to the processes described in WO 98/11128 and DE 199 52 146. The starting compounds of general formula (IV) are commercially available. Compounds of general formula (V) may be obtained by methods familiar to the peptide chemist from protected phenylalanines and amines of general formula HNR²R³.

The phenyalanine derivatives needed to prepare the optically pure compounds of general formula (V) may be prepared from the compounds of general formula

wherein Y and Z are as hereinbefore defined and R denotes an unbranched alkyl group, preferably the methyl or ethyl group, by racemate cleavage.

This racemate cleavage can be carried out using enzymatic methods, while only one enantiomer of the racemate is transformed and the mixture produced is then separated using physicochemical methods, preferably using chromatographic methods. A suitable enzyme system for this step consists of the enzyme Alcalase 2.4 L FG (Novozymes A/S; DK 2880 Bagsvaerd). The compounds of general formula (X) can then be converted into the enantiomerically pure compounds of general formula (V) by methods familiar to the peptide chemist.

If the group X in compounds of general formula (V) denotes the oxygen atom, the hydroxycarboxylic acids needed for the synthesis, of general formula

wherein Y and Z are as hereinbefore defined,

may be prepared from compounds of general formula (X), with the proviso that R denotes the hydrogen atom.

The compounds of general formula (XI) may be obtained by diazotisation of compounds of general formula (X) with a suitable diazotising reagent, preferably sodium nitrite in an acidic medium. If enantiomerically pure compounds are used, the corresponding enantiomerically pure hydroxycarboxylic acid compounds are obtained, and the configuration is retained during the reaction.

Another method of obtaining compounds of general formula (XI) comprises alkylating the compound

with correspondingly substituted benzyl chlorides, benzyl bromides or benzyl iodides of general formula

wherein X denotes a chlorine, bromine or iodine atom, analogously to methods known from the literature (Michael T. Crimmins, Kyle A. Emmitte and Jason D. Katz, Org. Lett. 2, 2165-2167 [2000]).

The diastereomeric products obtained can then be separated by physicochemical methods, preferably using chromatographic methods. The hydrolytic cleaving of the chiral auxiliary, coupling with amines of general formula HNR²R³ and cleaving the benzyl protecting group also provides access to enantiomerically pure hydroxycarboxylic acid compounds of general formula (V).

The starting compounds of general formula (VI) are obtained for example by reacting amines of general formula HNR²R³ with 2-(alkoxycarbonylmethyl)-3-aryl-propanoic acids and subsequently hydrolytically cleaving the alkyl group. The 2-(alkoxycarbonylmethyl)-3-aryl-propanoic acids required may be prepared analogously to methods known from the literature (David A. Evans, Leester D. Wu, John J. M. Wiener, Jeffrey S. Johnson, David H. B. Ripin and Jason S. Tedrow, J. Org. Chem 64, 6411-6417 [1999]; Saul G. Cohen and Aleksander Milovanovic, J. Am. Chem. Soc. 90, 3495-3502 [1968]; Hiroyuki Kawano, Youichi Ishii, Takao Ikariya, Masahiko Saburi, Sadao Yoshikawa, Yasuzo Uchida and Hidenori Kumobayashi, Tetrahedron Letters 28, 1905-1908 [1987]). Carboxylic acids of general formula (VIII) may be prepared from generally available starting materials in accordance with the processes described in WO 98/11128.

The compounds of general formula I obtained may, if they contain suitable basic functions, be converted, particularly for pharmaceutical use, into their physiologically acceptable salts with inorganic or organic acids. Suitable acids include for example hydrochloric acid, hydrobromic acid, phosphoric acid, nitric acid, sulphuric acid, methanesulphonic acid, ethanesulphonic acid, benzenesulphonic acid, p-toluenesulphonic acid, acetic acid, fumaric acid, succinic acid, lactic acid, mandelic acid, malic acid, citric acid, tartaric acid or maleic acid.

Moreover, the new compounds of formula (I), if they contain a carboxylic acid function, may if desired be converted into the addition salts thereof with inorganic or organic bases, particularly for pharmaceutical use into the physiologically acceptable addition salts thereof. Suitable bases for this include, for example, sodium hydroxide, potassium hydroxide, ammonia, cyclohexylamine, dicyclohexylamine, ethanolamine, diethanolamine and triethanolamine.

The present invention relates to racemates if the compounds of general formula (I) have only one chiral element. However, the application also includes the individual diastereomeric pairs of antipodes or mixtures thereof which are obtained if there is more than one chiral element in the compounds of general formula (I), as well as the individual optically active enantiomers of which the above-mentioned racemates are made up.

Also included in the subject matter of this invention are the compounds according to the invention, including the salts thereof, in which one or more hydrogen atoms are replaced by deuterium.

The new compounds of general formula (I) and the physiologically acceptable salts thereof have valuable pharmacological properties, based on their selective CGRP-antagonistic properties. The invention further relates to pharmaceutical compositions containing these compounds, their use and the preparation thereof.

The new compounds of general formula I and the physiologically acceptable salts thereof have CGRP-antagonistic properties and exhibit good affinities in CGRP receptor binding studies. The compounds display CGRP-antagonistic properties in the pharmacological test systems described hereinafter.

The following experiments were carried out to demonstrate the affinity of the above-mentioned compounds for human CGRP-receptors and their antagonistic properties:

A. Binding Studies with SK-N-MC Cells (Expressing the Human CGRP Receptor)

SK-N-MC cells are cultivated in “Dulbecco's modified Eagle medium”. The medium is removed from confluent cultures. The cells are washed twice with PBS buffer (Gibco 041-04190 M), detached by the addition of PBS buffer mixed with 0.02% EDTA, and isolated by centrifuging. After resuspension in 20 ml of “Balanced Salts Solution” [BSS (in mM): NaCl 120, KCl 5.4, NaHCO₃ 16.2, MgSO₄ 0.8, NaHPO₄ 1.0, CaCl₂ 1.8, D-glucose 5.5, HEPES 30, pH 7.40] the cells are centrifuged twice at 100×g and resuspended in BSS. After the number of cells has been determined, the cells are homo-genised using an Ultra-Turrax and centrifuged for 10 minutes at 3000×g. The supernatant is discarded and the pellet is recentrifuged in Tris buffer (10 mM Tris, 50 mM NaCl, 5 mM MgCl₂, 1 mM EDTA, pH 7.40) enriched with 1% bovine serum albumin and 0.1% bacitracin, and resuspended (1 ml/1000000 cells). The homogenised product is frozen at −80° C. The membrane preparations are stable for more than 6 weeks under these conditions.

After thawing, the homogenised product is diluted 1:10 with assay buffer (50 mM Tris, 150 mM NaCl, 5 mM MgCl₂, 1 mM EDTA, pH 7.40) and homogenised for 30 seconds with an Ultra-Turrax. 230 μl of the homogenised product are incubated for 180 minutes at ambient temperature with 50 pM ¹²⁵I-iodotyrosyl-Calcitonin-Gene-Related Peptide (Amersham) and increasing concentrations of the test substances in a total volume of 250 μl. The incubation is ended by rapid filtration through GF/B-glass fibre filters treated with polyethyleneimine (0.1%) using a cell harvester. The protein-bound radioactivity is measured using a gamma counter. Non-specific binding is defined as the bound radioactivity in the presence of 1 μM human CGRP-alpha during incubation.

The concentration binding curves are analysed using computer-aided non-linear curve matching.

The compounds mentioned hereinbefore show IC₅₀ values 10000 nM in the test described.

B. CGRP Antagonism in SK-N-MC Cells

SK-N-MC cells (1 million cells) are washed twice with 250 μl incubation buffer (Hanks' HEPES, 1 mM 3-isobutyl-1-methylxanthine, 1% BSA, pH 7.4) and pre-incubated at 37° C. for 15 minutes. After the addition of CGRP (10 μl) as agonist in increasing concentrations (10⁻¹¹ to 10⁻⁶ M), or additionally the substance in 3 to 4 different concentrations, the mixture is incubated for another 15 minutes.

Intracellular cAMP is then extracted by the addition of 20 μl of 1M HCl and centrifugation (2000×g, 4° C., for 15 minutes). The supernatants are frozen in liquid nitrogen and stored at −20° C.

The cAMP contents of the samples are determined by radioimmunoassay (Messrs. Amersham) and the pA₂ values of antagonistically acting substances are determined graphically.

The compounds of general formula I exhibit CGRP-antagonistic properties in the in vitro test model described, in a dosage range between 10⁻¹² and 10⁻⁵ M.

In view of their pharmacological properties the compounds of general formula I and the salts thereof with physiologically acceptable acids are thus suitable for the acute and prophylactic treatment of headaches, particularly migraine or cluster headaches. Moreover, the compounds of general formula I also have a positive effect on the following diseases: non-insulin-dependent diabetes mellitus (“NIDDM”), cardiovascular diseases, morphine tolerance, diarrhoea caused by clostridium toxin, skin diseases, particularly thermal and radiation-induced skin damage including sunburn, inflammatory diseases, e.g. inflammatory diseases of the joints (arthritis), neurogenic inflammation of the oral mucosa, inflammatory lung diseases, allergic rhinitis, asthma, diseases accompanied by excessive vasodilatation and resultant reduced blood supply to the tissues, e.g. shock and sepsis. In addition, the compounds according to the invention have a general pain-relieving effect. The symptoms of menopausal hot flushes caused by vasodilatation and increased blood flow in oestrogen-deficient women and hormone-treated patients with prostate carcinoma are favourably affected by the CGRP-antagonists of the present application in a preventive and acute-therapeutic capacity, this therapeutic approach being distinguished from hormone replacement by the absence of side effects.

The dosage required to achieve a corresponding effect is conveniently 0.0001 to 3 mg/kg of body weight, preferably 0.01 to 1 mg/kg of body weight, when administered intravenously or subcutaneously and 0.01 to 10 mg/kg of body weight, preferably 0.1 to 10 mg/kg of body weight when administered orally, nasally or by inhalation, 1 to 3 × a day in each case.

If the treatment with CGRP antagonists and/or CGRP release inhibitors is given as a supplement to conventional hormone substitution, it is advisable to reduce the doses specified above, in which case the dosage may be from ⅕ of the lower limits mentioned above up to 1/1 of the upper limits specified.

The compounds prepared according to the invention may be administered either on their own or optionally in combination with other active substances for the treatment of migraine by intravenous, subcutaneous, intramuscular, intrarectal, intranasal route, by inhalation, transdermally or orally, while aerosol formulations are particularly suitable for inhalation. The combinations may be administered either simultaneously or sequentially.

Categories of active substance which may be used in the combination include e.g. antiemetics, prokinetics, neuroleptics, antidepressants, neurokinine antagonists, anti-convulsants, histamine-H1 receptor antagonists, antimuscarinics, β-blockers, α-agonists and a-antagonists, ergot alkaloids, mild analgesics, non-steroidal antiinflammatories, corticosteroids, calcium antagonists, 5-HT_(1B/1D) agonists or other anti-migraine agents, which may be formulated together with one or more inert conventional carriers and/or diluents, e.g. with corn starch, lactose, glucose, microcrystalline cellulose, magnesium stearate, polyvinyl pyrrolidone, citric acid, tartaric acid, water, water/ethanol, water/glycerol, water/sorbitol, water/polyethylene glycol, propylene glycol, cetylstearyl alcohol, carboxymethylcellulose or fatty substances such as hard fat or suitable mixtures thereof, into conventional galenic preparations such as plain or coated tablets, capsules, powders, suspensions, solutions, metered dose aerosols or suppositories.

Thus other active substances which may be used for the combinations mentioned above include for example the non-steroidal antiinflammatories aceclofenac, acemetacin, acetyl-salicylic acid, azathioprine, diclofenac, diflunisal, fenbufen, fenoprofen, flurbiprofen, ibuprofen, indometacin, ketoprofen, leflunomide, lornoxicam, mefenamic acid, naproxen, phenylbutazone, piroxicam, sulphasalazine, zomepirac or the pharmaceutically acceptable salts thereof as well as meloxicam and other selective COX2-inhibitors, such as for example rofecoxib and celecoxib.

It is also possible to use ergotamine, dihydroergotamine, metoclopramide, domperidone, diphenhydramine, cyclizine, promethazine, chlorpromazine, vigabatrin, timolol, isometheptene, pizotifen, botox, gabapentin, topiramate, riboflavin, montelukast, lisinopril, prochloroperazine, dexamethasone, flunarizine, dextropropoxyphene, meperidine, metoprolol, propranolol, nadolol, atenolol, clonidine, indoramin, carbamazepine, phenytoin, valproate, amitryptiline, lidocaine or diltiazem and other 5-HT_(1B/1D)-agonists such as, for example, almotriptan, avitriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan and zolmitriptan.

The dosage of these active substances is expediently ⅕ of the lowest recommended dose to 1/1 of the normally recommended dose, i.e. for example 20 to 100 mg of sumatriptan.

The invention further relates to the use of the compounds according to the invention as valuable adjuvants for the production and purification (by affinity chromatography) of antibodies as well as in RIA and ELISA assays, after suitable radioactive labelling, for example by tritiation of suitable precursors, for example by catalytic hydrogenation with tritium or replacing halogen atoms with tritium, and as a diagnostic or analytical adjuvant in neurotransmitter research.
